I'm starting to think Texas may be the joke. But I can't remember if we have any decent, sane, non-barbaric Texans here and I don't want to offend, and besides which, I expect it's like anywhere, a lot of people are really good and decent and then you have people like this principal and this coach fucking it up for everyone else. But I can't remember ever being more ill at ease about reading a news story than this one.
A friend of mine on Facebook who is from Texas responded with "Oh, it's Dallas. You expect that crap to come out of Dallas." Obviously I'm not familiar with local Texan attitudes and practices.
